To all whom it may coac'ewt:

Be it known that I, ERNIE ADAMsoiT, a citizen of the United States, residing at Carrollton, in the county of Carroll and State of Georgia, have invented new and useful- Improvenients in AcetyIeneGenerators, of p which the following is specification.

The invention relates to generators, andmore particularly to the class of acetylene generators.

The primary object of the invention is the provision of an acetylene generator wherein the bell is fixedly and detachably mounted within the tank to permit the ready mounting of the same therein or its removal therefrom, the bell being equipped to carry the 'carbid holder and water admitting receptacle. v

A further object of the invention is the provision of an acetylene generator wherein the carbid holder is removably held within a water receptacle which is detachably hung within the bell and is so arranged with relation thereto as to prevent the choking of the gas delivery pipe or the stopping up of the same.

A still further Object of the invention is the provision of an acetylene generator wherein the tank carries resilient fingers adapted to act upon the bell to properly center the samewhe'reby it may be detachably fastenedwithin the said tank in a quickand convenient manner.

A still furtherobject of the invention is the provision of an acetylene generator which is extremely simple in eonstruction thoroughly reliable and eflicient in operation, and inexpensive in manufaeture.

lVith these and other objects in view, the invention consists in the construction, corn,- bination and arrangement of partsas will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the drawings Figure 1 is a vertical longitudinal sectional view through an acetylene gas generator constructed in accordance with the invention. Fig. 2 is a sectional view on the line 22 of Fig. 1. Fig. 8 is a sectional view on the lin'e 33 of Fig. 1. Fig. 4 is a fragmentary perspective view of the tank body and top raised therefrom. Fig. 5 is a fragmentary 's'ectional View throfigh the fastener for the lw'elter admitting receptacle carried by the e Similar reference characters indicate corresponding parts throughout the several VIQW'S' in the drawing.

Referring to the drawing by numerals, 5th? acetylene generator c'oni'p'ris'esa cylindrlcal tank 5 preferably constructed of imetal, although it may be made of any jother suitable material, and has its upper open end closed by means "of a removable cover or top '6 formed with a depending I marginal flange 7 provided at intervals with inwardly extending locking lugs 8 which 3 are adapted to "engage the c'aln faces of ribs or flanges 9 formed on the outer face of the tank 5 at .the open end thereof, the ribs or flanges 9 being separated to form entrance spaces 10' for the lugs 8 whereby on telej scoping the cover or top 6 upon the tank 5 the lugs 8 will pass through the spaces 10 to engage the cam surfaces of the ribs or flanges 9 so that on the turning of the cover or top 6 the same can be locked upon the tank and thereby effect a fluid-tight closure for the open endfof the said tank, the latter being 'o'artially filled with water through the open end thereof on the removal of the cover or to'p therefrom. Tapped or other; wise mounted in the side wall of the tank 5 is a drain cock 11 which is located contiguo-us to the bottom 'of the tank 5 so as to permit the proper draining of the tank and the removal of sediment or foreign matter therefrom.

Arranged within the tank 5 spaced from the top for cover 6 is a stationary ring 12 which is formed at intervals with legs or bosses 13 extending radially therefrom at the outer periphery thereof, each boss or leg being provided with a seat 14: in which is fitted one end of a spring finger 15 which depends into the lower portion of the tank 5, the ring 12 being positioned concentrically to the center of the tank 5 by the legs or bosses 13, and is seeuredtherein through the medium of the screw fasteners 16 -which pass through the tank 5, fingers 15 and engage in the legs or bosses 13 as shown, the spring fingers 15 being desi ned for a purpose presently described. 7

Removably fittedin the tank 5 is a cylindric'al shaped bell 17 provided with a closed top 18, while its opposite lower end is open, the bell being fastened at its closed top 18 to an upwardly arched spider 19 formed with an externally threaded rim 20, the ring 12 being internally threaded for the detachable engagement of the rim 20 of the spider therewith. The bell 17 has its open end terminating close to the bottom of the tank 5, while mounted in the side wall of the said gas bell near the closed top 18 thereof are holding pins or lugs 21 for the detachable engagement therewith of a receptacle or cup 22 which is formed with a flared open end 23 provided at intervals with bayonet shaped slots 24; receiving the lugs or pins 21, the cup or receptacle 22 being turned slightly whereby the said pins or lugs 21 will engage in the closed ends of the slots 24 for the secure fastening of the cup or receptacle within the gas bell 17 as shown.

The flared end 23 of the receptacle or cup 22 forms a bearing or annular seat 25 for the flared mouth 26 of a carbid holder 27- which is readily removable from the cup or receptacle when the same is detached and removed from the bell 17, the cup 27 depending within the cup or receptacle 22 and isformed with a screened opening 28 centrally in its bottom for communication with the cup or receptacle 22 whereby water entering the latter may pass through the opening 28 into the holder 27 for action upon the carbid which is held therein to produce gas.

Extending upwardly between the bell 17 and the cup or receptacle 22 is the vertical portion 29 of a gas delivery pipe which has its horizontal portion 30 passed through the tank 5 exteriorly thereof, the pipe being fastened or coupled to the tank 5 in any desirable manner, and the vertical portion 29 thereof terminates slightly spaced from the flared end 23 of a cup or receptacle 22 so that gas circulating between the latter and the bell 17 will'flow into the pipe and be delivered thereby to any suitable point, the.

spring fingers 15 being arranged in downwardly converging relation so as to act upon the bell 17 when inserted through the ring 12 in the tank 5 for the centering of the said bell to permit the quick and easy mounting and fasteningof the bell in position in the tank.

Rising centrally from the spider 19 is a stem 81 which terminates in a cross handle 82, the same being spaced from the top or cover 6, and this handle 82 permits the fastening of the rim 20 of the spider in the ring 12, or the unfastening of the said rim therefrom, it being seen that the gas bell 17 can be stationarily mounted in the tank 5 or removed therefrom.

In the operation of the acetylene generator,'the carbid is placed within the holder 27 which is inserted within the cup or receptacle 22 so that its flared mouth 26' will rest on the seat 25 formed in the said cup or receptacle and thereafter the latter is fastened in the bell 17 which is then stationarily mounted in the tank 5, the same being properly filled with water prior to the fastening of the cover or top 6 thereon. The cup or receptacle 22 at diametrically opposite points is formed with downwardly tapered slots 33 through which the water passes from the tank 5 into the said cup or receptacle 22 and as the water rises therein it will be admitted through the opening 28 in the carbid holder 27 to act upon the carbid therein for the generation of gas. During the generating of the gas the pressure thereof will-act upon the body of water, causing it to lower within the cup or receptacle 22 by driving the water therefrom back into the tank, the gas escaping from the said cup or receptacle 22 above the water level into the space between the bell l7 and the said cup or receptacle, whence the gas will flow into the vertical portion 29 of the pipe and be delivered through the horizontal port-ion 30 thereof to any suitable point for consumption. When the gas generated becomes low in quantity the water rises within the receptacle or cup 22 to mix with the carbid in the holder 22 thereby further generating gas until the pressure thereof reaches a predetermined degree, whence the water will be again disturbed and forced from the receptacle or cup 22 to permit the gas to escape therefrom and be discharged through the pipe as heretofore stated. The cup or receptacle 22 serves to catch sediment or minute particles of carbid, and in this manner the tank will remain clean and also the cup can be readily washed or cleaned when the bell is removed from the tank.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. In an acetylene generator, a tank, a supporting ring fixed interiorly thereof, a gas bell detachably engaged with the ring and depending within the tank, a slotted cup detachably engaged interiorly of the bell and having its major portion spaced therefrom, a carbid holder removably held within the cup, means extending between the cup and bell and leading from the tank for delivering gas from the bell to a point exteriorly of the tank, and means integrally formed with the bell for permitting the turning thereof for the fastening of the same in the ring or detaching it therefrom.
